Android is a mobile operating system developed by Google, based on the linux kernel and it is designed for touchscreen phones and tablets. Android has a growing selection of third-party applications, which can be used by the users by downloading and installing the application, or by downloading them using an application store program that allows its users to install, update, and remove applications and delete them if one doesn’t use them, from their devices. Google Play Store is an application store installed on Android devices that allows the users to download multiple applications just within the click or touch of the screen. Google Play Store allows users to browse, download and update applications published by the developers. There are more than one million applications available for Android in Play store. In a month of 2013, 48 billion applications were installed from Google play store.^[update]
